Gender-specific disease risks start in the womb - Pregnancy places competing demands on a mother's physiology: her body wants to produce a healthy baby but not at the expense of her own health. Therefore, she passes so-called "imprinted genes" on to her child to protect her body from excessive demands from the child. Genes inherited from the father however aim at getting as many resources for the fetus as possible. This battle of genes might be at the root of later life diseases.

Older people in assisted-living facilities sleep poorly - In a study of residents of assisted-living facilities in Los Angeles showed that 65 percent had clinically significant sleeping problems and that poor sleep was associated with declining quality of life and increased depression over a six month follow-up period.
